Examine the false statement.
Compounds are the smallest unit of an element that occur most commonly in nature.
Select the rewording of the statement that is true.
Compounds are the smallest unit of an element that occur on the periodic table.
Molecules are the smallest unit of a compound that occur on the periodic table.
Atoms are the smallest unit of an element that commonly occur in nature.
Molecules are the smallest unit of an element or compound that commonly occur in nature.
The false statement claims that compounds are the smallest unit of an element that occur most commonly in nature. To find the true statement, we need to select the rewording that accurately reflects the correct relationship between compounds, elements, and their occurrence in nature.
Let's examine the options:
Option 1: "Compounds are the smallest unit of an element that occur on the periodic table."
This rewording correctly identifies the relationship between compounds and elements in relation to their occurrence on the periodic table. However, it doesn't address their occurrence in nature, so we can eliminate this option.
Option 2: "Molecules are the smallest unit of a compound that occur on the periodic table."
This rewording correctly identifies that molecules are the smallest unit of a compound, but it does not address the occurrence of elements or compounds in nature. Therefore, we can eliminate this option.
Option 3: "Atoms are the smallest unit of an element that commonly occur in nature."
This rewording correctly identifies that atoms are the smallest units of an element, and it accurately reflects that elements commonly occur in nature. This option also addresses the occurrence of elements on the periodic table. Therefore, this could be the correct rewording that represents a true statement.
Option 4: "Molecules are the smallest unit of an element or compound that commonly occur in nature."
This rewording correctly identifies that molecules can be the smallest units of both elements and compounds. Additionally, it accurately reflects that elements and compounds commonly occur in nature. Therefore, this could also be a valid rewording representing a true statement.
In summary, both option 3 and option 4 could be the correct rewording that represents a true statement.
